Goblins and Gnomes having tech cities and every other race being in either a medieval city or a magical city. The lack of lore characters outside of Goblins and Gnomes utilizing technology on a consistent basis. The lack of NPCs outside of Goblins and Gnomes utilizing technology on a consistent basis.
Which means that a random Human doesn't walk up to an engineering trainer and learns how to become a Tinker on the level of Mekkatorque or Gazlowe. At most, a human learns engineering to craft some minor gadgets to help aid their class and their allies. Tinkers on the other hand have an innate ability to invent. They're like Tony Stark in the Marvel universe.
So while a warrior might learn engineering to build a bomb to toss at a forest spider to distract it so it can kill it with his sword, a Tinker will blast the spider with a laser cannon from inside their mech.
See above. The other being quality of gadgets made.Can you prove there is a distinction? Because as far as we know, there is no specific classification for what a Tinker does that makes them different from Engineers.
Except a Blood Elf Paladin is no weaker than a Draenei Paladin in gameplay or lore. It's merely a racial distinction. Engineering is like bottom level tech knowledge that Gnomes and Goblins teach to other races in order to make some coin, like all professions. It's nowhere near the high end level technology from tech geniuses like Mekkatorque, Blackfuse, Thermaplugg, and possibly even Gazlowe.If we say they invent, we already know Engineers also invent. If we say they build their own machines whereas a Engineer doesn't, then that's not sustained by lore, it's simply headcanon. There is no source of lore that makes a distinction that says 'Not all Engineers are Tinkers' because we don't know what the framework is.
I mean by all means, it could be a racial epitome, like Vindicator is used for Draenei Paladins or Blood Knight for Blood Elf Paladins. There is no lore that says otherwise.

I'm talking about the obvious differences between the engineering profession and the Tinker class. What are you talking about?
Do Tinker's build their own inventions using actual materials and tools? I don't know, that's never been properly explored. Again, with the advent of pocket factories it's quite likely that a Tinker could simply input the information they need and the factory mass produces it for them. Consider for example a Tinker using a turret versus a profession engineer building a turret; the Tinker is dropping multitudes of turrets which aren't misfiring, and they never run out of materials to build new ones. Meanwhile, the profession engineer has to constantly find materials and build new turrets. Those turrets misfire, are far weaker than the ones the Tinker is dropping, and simply don't measure up to the task of defending the engineer or their party.
That scenario would obviously support that belief, and make perfect sense on a class versus profession level.
